The NordLink HVDC project is a 1,400 MW submarine interconnector linking Norway and Germany. It became operational in 2021 and is one of Europe’s most important cross-border transmission projects, often referred to as the “green cable.”
The interconnector enables the exchange of Norwegian hydropower with German wind and solar, strengthening energy security, supporting decarbonization, and balancing intermittent renewable output across the two countries.
